I'm not sure about C#, but in JavaScript (Node.js):

function get_error() {
    return new Error('my error');
}

function do_throw(e) {
    throw e;
}

try {
    do_throw(get_error());
} catch (e) {
    console.log(e.stack);
}


results in:

Error: my error
    at get_error (/home/jesse/src/test.js:2:12)
    at Object.<anonymous> (/home/jesse/src/test.js:10:14)
    at Module._compile (module.js:413:34)
    at Object.Module._extensions..js (module.js:422:10)
    at Module.load (module.js:357:32)
    at Function.Module._load (module.js:314:12)
    at Function.Module.runMain (module.js:447:10)
    at startup (node.js:146:18)
    at node.js:404:3


The top frame is the construction (get_error) and the site of the throw
(do_throw) doesn't appear in the stack at all.
